THERMOACTIVE SHUTTERING PANEL WITH EFFICIENT THERMAL INSULATION Russian patent published in 1998 - IPC

FIELD: construction engineering. SUBSTANCE: thermoactive shuttering panel is intended for electrothermal treatment of concrete. Base of panel is made in the form of thermal insulating layer of stiff moisture- and temperature-resistant foam plastic material. Heating element is made of polyamide with current-conducting paper component. Heating element is applied to thermal insulating layer by means of hot-pressing method. Aforesaid embodiment of heating shuttering panel is most simple to manufacture and is acceptable for all systems of shuttering. EFFECT: higher efficiency. 1 dwg
